To all whom t may concern.' l

Be it known that I, FRANK YoKEL, a citizen of the United States, residing at Avalon, in the county of Allegheny and Sritate of Pennsylvania, have invented certain Vnew and useful Improvements "in Heating Stoves, of which the following is aspecification.'

This invention is for an improvement v1n gas heating stoves of the open front type, in which combustion takes place ina series of vertical open front columns or radiants, as they aretermed in the art. y h

The present invention has for its principal object to provide a stove wherein rthe several radiants are formed of two pieces of sheet metal, instead of being individually molded from fire clay, as is customary,and with the radiants so designed as to provide a. maximum radiatingsurface. The invention has for a further object to providefor the circulation of air around the radiants and out the top of the stove, whereby heating by convective currents is obtained and the eiiciency of thestove increased.

The invention may be readily understood by reference to the accompanying drawings, inwhich:

' Fig. 1 is a front view, partly in section and partly in elevation;

Fig. 2 is a vertical transverse section in the plane of line II#II of Fig. 1;

Fig. 3 is a horizontal section in the plane of line III-III of Fig. 2; and

Fig. 4 is a'transverse section on a large scale of portion of the two plates forming the radiants.

In the drawings, 5 designates the front bottom frame member of the stove, -and 6 are legs formed integrally therewith. Sup ported on this front membeigrand on rear legs 7, is a sheet metal casing having a back 8, sides 9, a top 10, and a depending front coping 11. The front of the coping is perforated at 12. f

Also, partially supported on the membr 5, is a horizontal plate 13 having a row of large holes 14 therein, to the rear of which is a second row of smaller holes 15. Below the plate 13 is a manifold 16 having a row of burners 17 on the top thereof, one burner projecting into each hole 14.

The several hollow open front columns or radiants 18, which extend up vfrom each hole 14, are formed of two sheets of metal 19 and 2O having outwardly pressed vertical ribs21 therein, theribs of one plate registering Vwiththose of the other, The Vcolumns are spaced apart'from each other, as shown in Fig. 3, so that each column is well removed from the adjacent ones; the areas of the plate between the ribsmeet at the' intervening space. rIhis arrangement gives a-large area with whichv airlcurrents may contact to obtain'eiicient results.' The ribs of the front sheet 19 are pierced as at 22 to form an ornamental grille. When the metal is pierced `at-20, itis not'entirely cut away, but is forced inwardly, as at 23, to provide heat absorbing projections inside the column.

Within the upper part of the stove is a hood 24, into which the top of the radiants project. end of the stove to theV other, is spaced away from the top and back walls of the stove, and has ya centralrearwardly extending' outlet r25 which may connect with a suitable pipe to a flue. Being spaced away from the top and rear of the top part of the stove, the hood lserves to heat air inthe top part of the stove, from whence it passes into the room through the perfor-ations 12. Fresh air, at the bottom of the stove, rises in back of the radiants, circulating around them and into the top of the stove. In this manner, the lair in a room may-be heated by contact with the heated parts of the stove, and the heat of combustion distributed without mingling the products of combustion or unburnt gases with the air.

A stove as thus constructed is simple and rigid, and Amay be cheaply .manufactured. If desired, the radiants may be painted white to render the stove more at.

tractive. Copper reflectors may be placed at each vside of the open front of the stove, as indicated at 26. y

' I claim as my invention: Y

1. A stove comprising a casing, a plurality of burners in the lower part thereof, and a pair of vertical plates mounted over the burners having separated oppositely pressed vertical ribs therein, the ribs of one plate registering with those of the other whereby vertical hollow columns are formed, one of said columns being disposed over each burner, the ribs of the plates being separated by intervening flat areas whose inner faces contact.

2. A stove comprising a casing having an open front, a rear wall, and a hollow perfo- This hood, extending from .one

rated upper portion, a plurality of burners in the lower part of the stove, radiants eX- tending upwardly from the burners, said radiants being spaced forwardly ol the rear wall of the casing and providing an air circulating` space between the radiantsand the rear wall and in which air may contact directly with the radiants, a yhood in the upper hollow part of the stove having a flue coninaction, said hood being spaced from the back wall of the casing, said radiants extendinginto the hood, the -baclr lspace at .the vrear of the radiants extending upwardly vpast the hood whereby air heated in the air space by direct Contact withithe radiants may How out the perforatedtop of the stove whilethe gases of combustion troni-the radiants may be carried out the tlue.

n; st ve comprising a casing having an open front, side and back walls, vand va hollow top -portionot,a horizontal supporting -member in the lower part ot the stove, a rowot' spacedapart burners in openings in the supporting member, a pair o' vertical plates mounted on ,the supporting ineniber over the burners, said plates having contact.- ing :faces in which are oppositely pressed ribs to torni hollow columns between lthe plates, one ot the .plates lniving said ribs perforated, said'ribs on each plate being spaced apart, with the columns being positioned over the burners,a hood inthe hollow upper part of the stove into which the gases from the columns may pass, said hood having a -rtlue outlet therein, the yhood being spaced 'from the top and rear walls o1' Athe upper part of the casing, a continuous air passage being provided at the back of the plates trom the top to the bottoni ot the stove, and perforations inthe top part of the casing through which air rpassing through 'the space `behind `the burners and in contact with kthe hood may emerge into the room, the plates forming a partition between the ifi-ont and back of the stove.

1l. Radiants tor heating stoves con'iprisinp` a pair ol adjacentl plates having register-ing oppositely formed vertical channels therein. which channels are spaced apart from those at eachside thereof, having vtlat surfaces being provided between z:the channels ot .the respective plates which.contact with the corresponding flat surfaces ot the otheigplate, ythe channels of one of the plates being perfoanted, the. said channels `at .teach side of .the pla te being separated so as .to permitot the circulation of air thereabout.

i radiant velement for heating stoves comprising a pair of sheet n'ietal plates V-having oppositoly pressed .ribs formed therein,

the ribso'l' each rplate having sides which are spaced away troni those oil` the .next adjacent plate, intervening ilat snr'taces .being provided between the ribs, therribs and flat surfaces of the two plates registering thereby forming separated hollow columns with the respective l'lat surfaces contacting, ,the ribs of one -plate having perl'orations therein, the metal removed by perforatiiig being` only vpartially severed and projecting into the hollow columns.

In testimony whereof aiiix mysi gnature.
